    I’m planning to reboot as long as I can to heal my severe PIED. My dick is small and tiny and it shrank one day over the course of a weekend, after masturbating and before that I was edging hardcore for days/weeks prior to that.

    I hope it’s porn-induced.

    Constantly stimulated as in how often, are we talking here?
     
  3. It depends on the severity of arousal as well but i would say as an absolute limit if you're long term having no release whatsoever then limiting the accidental leakage of precum to once a week or ideally way less

    Basically you just don't want to stimulate the systems involved in ejaculation without release everyday

    I'd like to keep this thread science based; it would be great if you would cite the studies @im_broken with these two findings so that we can read them too.

    So if I trigger my sexual arousal system without any ejaculatory release, it could start bringing on Prostate cancer?

    So if I trigger my sexual arousal system without any sexual release a few times a day, I am sure to get prostrate cancer? Now I’m concerned.
     
  7. No, what I mean is that long term (talking years or decades here) inflammation of the prostate will increase your risk generally, it's not a guarantee, I'm saying long term inflammation is a risk

    Ooh gotcha. Sorry, I wasn't sure and pretty sure that I overreacted.

    Still, I hope precum isn't detrimental to any reboot that heals the brain. Not that I want to be edging 24/7, but neither do I want to lead it to PMO. I fully understand the effects of edging.

    I'm troubled by these posts.

    Firstly the obvious. I know people who have smoked like chimneys all their lives and lived to a ripe old age and then died of something unrelated to smoking. Smoking causes cancer. Are smokers sure to get cancer? Of course not. Why speak in terms of certainty about something that's clearly all about probabilities?

    Secondly if you don't want to read a thread then don't. There are more threads on here than anyone could possibly keep abreast of, read the ones that resonate with your reboot experiences.

    I was hoping that this thread was for people who wanted to look at the research around prostate cancer and masturbation, regardless of whether the pieces of research supported the 'no masturbation' lifestyle. I was worried that people here are too zealous and tend to dismiss outright anything that suggests abstaining from masturbation is risky. I wanted a thread where we could objectively look at the evidence and decide on the risk for ourselves. Risk, not certainty.

    That first one is brilliant, thank you @im_broken. Real shame that the full PDF is $50 though. I'd love to read that, did you read it? The second is frustrating as the article starts by saying
    but does not go on to cite the academic paper. I cannot find it at all, did you?

    Do you have any citations behind this too:

  11. I have not read the full article sorry, the bit about stimulation was just from my personal experience, having edged without release for hours everyday on and off for a year i developed intermittent prostate pain that went away once I quit, it was just a guess based on that and the logic that if you're not telling your prostate to produce fluid without release in theory there should be very little inflammation and therefore reduced risk. This theory does not take into account hormones such as DHT though

    I'm sorry i don't have a source for the newspaper article

    @Kenzi found two great WebMd pieces about this subject:

    Can Sex, Masturbation Affect Prostate Cancer Risk? (WebMd, June 2017)

    This one's got a great overview of what we do not (yet) know:
    Masturbation and Prostate Cancer Risk (WebMD, January 2009)

    This one's a news piece about a study published in the January issue of BJU International

    Don't fap if you feel it's affecting your life in a negative way. It's really not that complicated.

    Sorry to be blunt @Infinite spirit, but as I have mentioned already I want this to be a science based thread on the relationship between masturbation and prostate cancer. If you have any studies to cite, or articles that summarize studies to post then please post them. Otherwise please do not move the thread off from that narrow topic.

    If you ask me these studies are complete bullshit. Too many unaccounted variables in them to have any statistical meaning.

    " The researchers asked men to answer questions about how often they ejaculated. Then they tracked almost 32,000 of these men for 18 years.
    The researchers found that guys who did it the most (at least 21 times a month) had about a 20% lower chance of prostate cancer, compared with those who did it less (4 to 7 times a month). That was true in several age groups."


    My first problem with this "major" study (and all other I came across) is that it didn't measure or ponder all other known risk factors that can contribute to prostate cancer development:

    1. inherited mutation of BRCA2 genes and Lynch syndrome
    2. diet (red meat or high-fat dairy products, low fruits and vegetables intake and maybe calcium are all known risk factors)
    3. obesity
    4. smoking
    5. chemical exposures (especially estrogen-like compounds, including monomeric bisphenol A (BPA))
    6. prostatitis (through inflammation of the prostate gland)
    7. gonorrhea or chlamydia infections (through inflammation again)
    8. vasectomy
    9 sedentary lifestyle

    https://www.cancer.org/cancer/prostate-cancer/causes-risks-prevention/risk-factors.html
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4537833/

    Study that ponder or equates all these factors would be needed to give viable answer to question does ejaculation really lower chances of prostate cancer. Such study would be extremely difficult if not impossible to do. But as it stands, results of current studies have too serious methodological deficiencies to be taken seriously.

    @Bogo Biggins, is this about the same paper I started this thread with, i.e. Ridera, Wilsona, Sinnotta, Kellyc, Muccia, & Giovannuccia's 2016 paper Ejaculation Frequency and Risk of Prostate Cancer: Updated Results with an Additional Decade of Follow-up? If it is I would love you to expand your criticism here. What, specifically, is wrong with the experimental design and data presented?

    Actually reading your post again @Bogo Biggins you may already cover specific criticisms:

    Is that the authors' fault? They published in European Urology which seems a pucker journal. Surely the public interest will send a clear message to researchers that we need more studies, there is a thirst for more knowledge about this. I think I would be more worried if the paper was ignored. It's good that there is something about the dangers of (porn and) masturbation in the Zeitgeist.

    True, this is not how people on NoFap would have designed the experiment, but I would expect the medical implications of infrequent masturbation to be close to no masturbation, wouldn't you?

    Indeed, this is why it is so important to check the effect size and not just the P value. But for me this was good news. Sure, they found a statistically significant increase in risk, but the magnitude of the increase was small. Hence it is a risk I am willing to take (but it is a risk).

    Does this matter? Intuitively I would expect medics' prostates to behave the same as yours or mine. Do you have a reason to suspect that they are pathologically different?

    They use EPM (ejaculations per month) so >20 does not seem unusual, especially in the past behaviour of members here.

  18. Thanks @kropo82, my original criticism was about the preliminary paper - hadn't seen this later paper. Will read it carefully and give my thoughts. Great find.

  20. TBH I still have not got around to this yet. I will though. I also plan to put an entry into my own journal in the not-to-distant future discussing a variety of papers that give pros- and cons- to a PMO free lifestyle, and this is one of them, so will probably do this at the same time? At the moment I have been focusing on reading around hunter gatherer tribes in relation to masturbation.
